PRAGUE, April 17 (Reuters) - Telefonica O2 Czech Republic first quarter net profit <
> is expected to have increased by 15 percent due to lower amortisation and taxes, a Reuters poll showed on Thursday.The average estimate in a poll of 10 analysts was for net profit of 2.65 billion crowns ($171.1 million), up from 2.31 billion in the first three months of 2007.
The biggest Czech telecommunications firm, majority owned by Spain's Telefonica <TEF.MC>, has seen a gradual decrease of its amortisation costs after massive investments in its fixed and mobile networks in the past.
The company should also benefit from a corporate tax cut which took effect in January, analysts said.
Revenues are expected to be 2 percent higher year-on-year at 15.55 billion crowns, as growing mobile and data services offset falling demand for fixed lines.
"We do not expect anything else but confirmation of existing trends," said Ondej Moravansky, analyst at brokerage Cyrrus.
"Despite lower revenues in the most important fixed-line segment, which is traditional voice services, we expect overall revenues from fixed lines to have rather stagnated, as the expected fall should be compensated by revenues from other activities," he added.
Core profit, or operating income before interest, tax, depreciation and amortisation (OIBDA), is expected to be 2 percent lower year-on-year due to rising marketing costs and investments into the Slovak mobile arm rolled out last year, the poll showed.
Shares in Czech Telefonica, the former fixed-line monopoly, have lost 20 percent over the last year to trade at 14 times forecast 2008 earnings (P/E) on Thursday, compared with the DJ Stoxx European telecoms index <.SXKP> trading at a P/E of 12, according to Reuters Estimates.
